Why you can't trust your calculator, or What is 48/2(9+3)?

Good lord, when I was in school, we did not use any other symbol than plus, add, divide, multiply, fractions were used, not percentages, long division
was pain, never mastered it, however, I was good in history, writing (pen and paper), geography, and basic science, like water is two atoms of
hydrogen and one of oxygen, actually that's all I do remember of that lesson!

"2(9+3)" is ONE term and cannot be distributed using reciprocals unless it is used as a whole. It MUST be solved before any other math is complete.
Just as 2x is one term, and 2 * x are two terms in the equation. Were it written as "2 * (9+3)" that would make two terms.

The latter, "2 * (9 + 3)" is explicit, as in this is exactly how you want it evaluated expression, but "2(9+3)" is implicit as it is one term and it
is implied that it will be solved for before any other calculation can depend on it. The fact the "2" is directly adjacent to the parenthesis should
be sufficient for anyone to know that it is a direct part of that calculation. It is like 2x, not 2 * x where distributive and commutative properties
work without fail.

This is where some things fall apart: not realizing or recognizing what term or factor in an equation is an independent or co-dependent entity.

Wrong. There is a reason the older calculator answered incorrectly (2) and every calculator sense then answers as 228. There really is no other way to
interpret it without adding/changing or misinterpreting the problem.

No. Wrong. There is an implied multiplication sign between the 2 and the "(." Following order of operations you are left with 48/2·12. Then
following order of operations again you solve left to right.

You guys are wrong and I dont understand how you can over complicate it. The older calculator was incorrect. The consensus of the article even says
288. I can type it into mu smart phone and when I put a parenthesis it automatically puts an multiplication symbol between the number/letter and the
parenthesis.

Makes sense to me. However, it all depends on how the equation is written. So after doing the parentheses the division has to be done first. With the
way it was wrote; how can you build a 24x12 box without first dividing your 48x box?

If you think the answer is 288, please read my post here. Its algebra
based solution with simple substitution for the proof of work.
It is very clear the answer is 2.

The reason your calculator show 288 because of - "immediate execution", the calculator DOES NOT KNOW about the parentheses/bracket/() before hand. A
human simply will see the () and solve it first, calculator simply solve the keyed input immediately on the spot and did not see the () until you key
it in, thus giving wrong answer.

Please stop replying to this thread so tl;dr people can see the solution.

Yes calculators DO know about parenthesis before hand. The answer is 288 when you do parenthesis first.
We arent talking about cheap calculators. Hell my calculator wouldnt have parenthesis inputs if it didnt know their purpose.

The implicit function xy, where x=2, y=(9+3), can be written as 2(9+3). The result of this must be resolved before any further math can be completed.
Pure, simple, true.

But for fun, again....
48 / 2(9+3) and you can't solve the equation until 2(9+3) is solved first, since as mentioned 2(9+3) is one term in the equation and cannot be
explicitly distributed across the equation with having been solved for first (i.e. = 24).

2(9+3) is ONE term and must be solved for before continuing evaluation of the equation.

Multiplication by juxtaposition. Nothing much else needs said, as that is the consensus of the mathematical community.
That is also what I was taught from 1982 through 1988 by my pre-algebra, algebra, geometry and trig teachers.
I'm sorry your teachers weren't up to snuff.

Imagine these thoughts applied to E=MC^2. If M = 48 and C^2 = 1/2(9+3) what would your answer be?
